Attention-deficit hyperactivity disorder (or ADHD) is characterized by a number of symptoms that begin in childhood, including:
- Problems with attention, concentration and organization
- Impulsive behaviors
Some people will have these symptoms minus the hyperactive fidgeting, sometimes referred to as ADD.
There is no single test for ADHD/ADD, which is a complex condition and is sometimes difficult to diagnose.
It is important to have a thorough evaluation since these symptoms could be the result of other conditions or factors not related to ADHD.
